Enigma 1050 is about real world usability, not big power outputs. On the right you can see what we found on the dyno and you can also see what we love about this engine. Look at the torque curve – nice and flat. And the power curve, wonderfully linear.
This adds up to an engine with bags of pull from almost anywhere in the rev range – ideal for road use. 121 bhp is enough to propel the standard bike to a top speed of 152mph, 0-60 in 3.17 seconds and 0-100mph in 6.76 seconds. That’s plenty quick enough to give us the right balance between power output and handling.

We’ll add a bit more power with an Austin Racing exhaust and a fuel remap which will be carried out by PDQ Motorcycle Developments. There’ll be a bit less weight as well so we will be able to improve on the standard power to weight ratio of 0.55bhp per kilogram. Performance will be more than adequate and the delivery will be superb.

Triumph Motorcycles Ltd have allowed us to use some of the Cad Drawings of the 1050 engine. You can see them here.
